No idea. You can try to use IsoBuster under WINE or try to find a similar *nix tool. Or you can rip a couple of separate sectors with DIC, it allows to extract ranges. Like, to rip -5 to -1 and leadout to leadout+5, for example.

Because the method is excellent, is the TOC of the hack music CD 99 minutes?
99 minutes is needed for DC, for normal CDs you can take any pressed music disc, but its total size should not be smaller than your target data CD's size.

Is the latest IsoBuster available in Wine?
The reason that .sub (subcode file) does not exist in database is
https://wiki.redump.info/index.php?title= … nformation
As written in
Because there is no error correction code, can not copy correctly?
Can't I get the correct subcode even with PLEXTOR?

Depends on whether to fix all the small read errors and mastering errors or not. If yes - can be copied quite easily with stable results. Otherwise, you need many rereads of the same disc on 2-3 different drives. We have an experimental subchannels reading tool if you want to test your discs and drives.

Even if PLEXTOR can read SubCode correctly, it is not in DB because .sub is unnecessary?
Is there no problem even if the .sub of the protected CD that uses the SubCode is not in the DB?
What is that experimental SubCode reading tool?

Plextors have weak lasers and they read subchannels worse than other drives. So, don't say "Plextor can read subcode correctly".
They have a pack subchannels reading mode, but it can be used for CD+G discs only, since it destroys any unusual data in R-W channels (same for 0xD8 when used for reading the subchannels in some cases), so, better not to use.

DB only supports libcrypt and securom subs for now.

Subdump.

I'm sorry.
If PLEXTOR is not good, which drive is better and which method is better?

What is unusual data?
F1ReB4LL wrote:Subdump.
Where can I download subdump?
I'm not familiar with the CD scramble, is there any page detailing it?
Where are the securom and libcrypt databases?

My Optiarc AD-7200A reads the subs with less errors, for example.
blemm wrote:What is unusual data?
Any non-CD+G data in R-W areas. For example, many PSX games have a specific sequence there that consisists of 0x01, 0x02, 0x03 bytes, Plextor's cooked sub reading mode wipes it.

On this forum.

The Q channel files (.sbi, .lsd) of libcrypt and SecuROM (~ v3) were in the db of redump, I overlooked it. (PSX was also at
http://psxdatacenter.com/sbifiles.html)
What is the difference between .sbi and .lsd?
.sbi can be created with psxt001z, but how do I create .lsd?
Can I create .sbi and .lsd with subdump?

lsd contains more data, but both are technically cut-off sub files.
blemm wrote:Can I create .sbi and .lsd with subdump?
Directly - no, .sub files only. You can probably convert them into sbi and lsd somehow (but what for? sbi and m3s files are only useable with psx emulators).

Is it for running on an emulator?

What is .m3s?
